SAFETY wrNDow-CHAIR.

Specification of Letters Patent.

Patented May 26, 1914.

Application filed May 24, 1913. Serial No. 769,616.

To all whom it may concern:

Be it known that I, NAZARENO Sciccrrr- TANI, a citizen of the United States, and resident of New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Safety Window-Chairs, of which the following is a specification.

The object of my invention is to provide simple and efficient means to enable a chair or seat to be secured within a window frame, as over the window sill, to enable a person to sit in the window upon the chair with safety.

In carrying out my invention I provide a window frame or sill with a retainer, over which I place a chair or seat having one or more members to coact with said retainer, `and to the chair or seat I attach a clamping device adapted, when set to press against the window sill, to retain said members connected to said retainer, whereby the chair will be firmly clamped in position upon the window frame or sill. The chair is preferably provided with a suitable back and one or more legs to rest upon the outer sill or stone-work of the building, whereby a person may sit in the window upon t-he chair or seat, and may raise or lower the window sashes as required for cleaning the latter, etc.

My invent-ion comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein- Figure l is an inverted plan view of a chair or seat equipped with my improvements; Fig. 2 is a cross sectional view illustrating my improvements in position in a window; Fig. 3 is a front view thereof; Fig. 4 is a section on the line 4, 4, in Fig. 2; Fig. 5 is a detail illustrating `a modification; Fig. 6 is a plan view illustrating a modified arrangement of the retainer and members upon the chair tocoact therewith; Fi '7 is a section substantially on the line 7, in Fig. 6, and Fig. 8 is a rear view of Fig. 7.

The numeral l indicates a chair s-eat shown provided with a back 2 and having one or more legs 3 at the outer or rear portion adapted -to rest at 4 outside of the window. The seat l is provided with one or more members 5, shown in Figs. l to 4 bent in substantially Z-form, having their free .ends 5a spaced below seat 1 and projecting forwardly in position to enter the corre* sponding openings 6a in retainer or bar 6 that is secured lengthwise upon the window sill member 4a, as by screws, I have shown seat l provided with two members 5, and retainer or bar 6 having two openings 6a spaced to correspond with the members 5. Adjacent to the forward edge o f seat l is a clamping .device shown comprising a bracket or the like 8 secured upon the bottom of the seat, as by screws or bolts, and having a threaded opening receiving a screw 9 extending longitudinally of the seat, partly beneath the same, and projecting forwardly beyond the seat, said screw having a suitable handle 9a, and said bracket is provided with a guideway 8EL receiving a clampin slide 10 having its rear portion 10*1 ext-ended f down in front of the inner end of screw 9, and having its outer or front portion 10b suitably extendedv down and shaped to fit against the project-ing portion 11 of the window sill 12, the portion 10b having an opening freely receiving the screw 9. Where the window sil-l is not provided with such a projecting portion 11 built with the sill, .a suitable projection lmay be fastened on the front of the sill or window frame, as indicated at 13 in Fig. 5. to receive the hooked or bent end portionrl()b of slide 10. At 14 is a spiral spring shown coiled around screw 9 and extending between bracket 8 and the downward portion 10b of slide l0.

Instead of providing a single retaining bar 6 vwith a pair of spaced openings 6a, I may provide two separate retainers each having an opening 6a and suitably spaced apart, as shown in Fig. 8, and shown secured to the outer edge of the sill member 4a. In

this construction also, instead of the free ends of the projecting portions 5 of the `members 5 extending forwardly beneath the seat, as in Figs. 1 to 4, they -extend downwardly, to enter the openings 6a, which are shown extending upwardly in Figs. l6 to 8 instead of horizontally as in Figs. 1 to 4. For this purpose the end portions 5a of members 5 are shown extending from the sides of the chair downwardly, and shaped to extend forwardly at an angle to the vertical, the openings 6a being correspondingly shaped (Fig. 7), whereby when the clamping slide 10 is fitted against the sill and drawn tight, the parts 5a will be locked firmly in the corresponding openings of the retainer member 6.' The retainers 6 may be spaced apart a distance greater than the width of the chair seat, the projections 5a extended correspondingly beyond the sides of said seat, whereby the openings 6L may be readily seen when the projections 5L are applied thereto.

My improvements may be made in suitable sizes and adapted to be applied in connection with windows of stone, brick, frame and other buildings, and so proportioned as to readily fit windows of different dimensions, as required, so that the parts may be fitted to a window with little difficulty and without interfering with the ordinary use of the window. /Vhile I have shown two members 5 on the chair, and two corresponding retaining openings 6a to receive the same, it will be understood that any desired number of such members and openings may be provided.

W'hen the chair or seat is to be used the screw 9 is unscrewed to permit the hooked end 10b of slide l() to extend outwardly as far as required, the projecting` ends 5a of members 5 are then passed through the corresponding opening 6@ of retainer 6, from the outside inwardly, in Figs. l to il, and from the top downwardly in Figs. 6 to 8, then the end l0b of slide 10 is placed in front of the projecting portion 1l or 13 of or on the window sill, and screw 9 is rotated, pushing against the depending part 105l of slide l0, thereby causing said slide to move inwardly and its hook-like part l()b to engage the projecting portion on the front of the sill, whereby the chair or seat is firmly clamped upon the sill in position to enable a person to sit with safety on the chair, with the back 2 of the chair outwardly with respect to the window. lNhen the chair is to be removed the screw 9 is unscrewed, and spring let pushes slide l0 outwardly, releasing the hooked part 10b from the sill, enabling the projections ZL of members 5 to be released from the retainer, and the chair lifted out from the window.

By means of my improvements a person may fasten the chair in the window and sit upon the chair in the window with safety for cleaning the windows, for receiving the benefits of the fresh air, etc., and my improvements will be found etiicient in use, simple in operation, and cheap to manufacture.

Having now described my invention what l claim is l. The combination of a base having means to connect it to a support to prevent the base from rising, a clamping device comprising a bracket secured upon the under part of the base and having a guideway and a threaded opening, a screw fitted in said opening, and a slide in said guideway over the screw, said slide having a rear portion extended downwardly to engage the screw on one side of the bracket and having a forward clamping portion on the opposite side of the bracket.

2. The combination of a base having means to connect it to a support, a clamping device comprising a bracket secured upon the under side of the base and having a guideway and threaded opening thereunder, a screw fitted in said opening and projecting on opposite sides thereof, a slide in said guideway above the screw, said slide having a rear portion extended downwardly to engage the inner end of the screw behind the bracket and having a forward clamping portion receiving the outer portion of the screw, and a spring interposed between said bracket and slide.

8. rlhe combination of a base having a forwardly facing hook to connect the base to a support to prevent the base from rising, a clamping device comprising a bracket secured on the underside of the base and having a guideway and a threaded opening thereunder, and a slide below the base fitted in said guide-way and having a downward portion at its inner end on one side of the bracket, and a downward hook-like portion at its outer end on the opposite side of the bracket, the latter portion being provided with an opening, a screw passing freely through said opening and meshing in said threaded opening in the bracket, the inner end of said screw being adapted to bear against the inner downward portion of the slide to pull said base and its hook to clamp the base on said support.
